Wild buckwheat is a European native. It is a vine that snakes along the ground or clambers over other plants or anything
else it can latch onto, winding itself in a clockwise direction around supports. Plants are up to 3' (1 m) long.
At points where leaves attach there is an ocrea, or sheath.
Leaves are alternate and roughly triangular to heart-shaped, with smooth edges. The lower corners of
each triangle are pointed inward toward the leaf petiole (stem). Leaves are ½-2" (1.5-6 cm) × ¼-1" (7-30 mm) wide. Flowers are small, ⅛" (4 mm) each, in long thin clusters, sort of weird-looking, greenish-white to greenish-pink.
